I²C bus buffer

21 July 2010 Telecoms, Datacoms, Wireless, IoT

Intersil has released a new series of 2-wire bidirectional I²C buffers that enable error-free data transmission in heavily-loaded I²C bus configurations. The ISL3300x series, which includes the ISL33001, ISL33002 and ISL33003, are suitable for use in servers, networking and telecommunications infrastructure equipment, and other applications that need hot swap board insertion and bus isolation. All three versions are capable of 400 kHz operation (I²C fast-mode data rate) and operate on 2,3 V to 5,5 V supplies. They also include rise-time accelerator circuitry to improve signal integrity and reduce power consumption from passive bus pull-up resistors. The ISL33002 and ISL33003 incorporate a logic level translator, so devices can be interfaced at mixed logic voltage levels. The ISL33001 and ISL33003 include an enable pin for low current shutdown, while the ISL33002 provides an accelerator disable pin.
